Select the correct navigational path to freeze the top row of your worksheet. Select the panes you wish to freeze. Click the tab
Artemon [7]

Yeah, Your steps ar correct. Let's analyse those steps more easily by the following steps:

\Large{ \boxed{ \bf{ \color{aqua}{Freeze \: panes:}}}}

Freeze panes is a feature in spreadsheet applications, such as Microsoft Excel, LibreOffice Calc, and Google Sheets. It "freezes" a row or column, so that it is always displayed, even as you navigate the spreadsheet.

❍ Freezing panes is especially useful if your spreadsheet has a header row, that you want to always be visible.

  • Select the row below the row(s) you want to freeze. In our example, we want to freeze rows 1 and 2, so we'll select row.
  • Click the View tab on the Ribbon.
  • Select the Freeze Panes command, then choose Freeze
  • Panes from the drop-down menu. ...
  • The rows will be frozen in place, as indicated by the gray line.

The question is incomplete as the scenarios are not given that were to be matched by the given encryption algorithms.

By finding the question from internet i have attached the image of the scenarios in the form of table and answered below accordingly

<h2>Answer:</h2>

<u>Scenario A:</u>

Advanced Encryption Standard (AES) is a technique that uses 256-bit cipher texts for encryption process. The data encrypted by AES cannot be attacked and even it cannot be decrypted unless a brute-force search is used through all of possible 256-bit keys.For mobile security it is known as one of the best algorithms.

<u>Scenario B:</u>

Following are the techniques of encryption used for given scenario:

  • ECC
  • Digital Signature
  • AES
  • Blowfish

<u>Scenario C:</u>

Following are the techniques of encryption used for given scenario:

  • ECC
  • Blowfish

<u>Scenario D:</u>

Secure Sockets Layer (SSL) - SSL is a protocol that is commonly-used for managment of the message transmission security over the Internet)

What are the arguments for writing efficient programs even though hardware is relatively inexpensive?
Ainat [17]

Answer: Even though the hardware is inexpensive the writing of program is not efficient through this method as proper development of program is necessary for the clear execution due to factors like:-

  • The facility of writing program even the cost of hardware is less but it is not a free facility.
  • It also has a slower processing for the execution of the program
  • The construction of the efficient program is necessary for the compilation and execution of it rather than poorly constructed program is worthless and inefficient in working.
